Everything comes from free public data: the National Weather Service, the National Hurricane Center, the Storm Prediction Center, NEXRAD radar from the Iowa Environmental Mesonet at Iowa State University, and NOAA nowCOAST. Warnings cover the United States, and the radar the lower 48 states. Instant notifications need an iCloud account.
